Types 1098-EGR and 1098H-EGR Pressure Reducing Regulators
www.emerson.com1. The pressures shown in the table are the minimum supply pressures required by the pilot. If the inlet pressure is less than shown, an external pilot supply is necessary. Principle of Operation The pilot-operated Types 1098-EGR and 1098H-EGR regulators both use inlet pressure as the operating medium, which is reduced through pilot operation to
